What software for DIY COREXY CNC Pen Plotter?

Projects Interfacing w/ Software on the Computer
1

Hello all,

I would like to create a COREXY CNC Pen Plotter.
I'm planning on using an arduino uno with a cnc shield, to grip the pen a small servo motor and for the XYZ movement, I will use 3 nema 17.
I have 2 criteria I need to fill.
That is automatique tool change like this :

And to be able to apply preasure, for calligraphique writting like so :

So then, the question I have is what software should I use to combine all of this?

Thank you all. :slight_smile:

Why X, Y and Z moves AND a servo for raising the pen? I would use the Z for that. There are only 2 steppers in the picture, X and Y....

Hello,

The small servo is for gripping and ungripping the pen. Then 1 nema 17 for X, 1 nema 17 for Y and another for Z.

Is that clear?

To upload on the arduino, I found GRBL, that is quite commonly used. So that would fit I think so. But I still need an UGS (Universal G-Code Sender).

Okey, automatic "tool change". I missed that. A little stepper and a spring might be more easy to operate, not punching holes in the paper.

Know that NEMA17 tells nothing but the mounting face of the stepper... Use M3 screws and a specified distance between the holes...

G code sender.... Google gives this: G code sender - Sök (bing.com)

I was using one G code sender but it's lost in a computer that crashed not long ago. I have to ask the Tuber that tipped me about it. Else I would tell You. The name was something like "Universal G code sender".
